10 LFO TRIANGLE
The LFO TRIANGLE socket outputs a simple triangle
waveform, but it can be altered by modulating the LFO
RATE or triggering the LFO RST to get some complex
modulation shapes.
11 LFO PULSE
The LFO PULSE socket outputs the PULSE wave in sync
with the TRIANGLE wave.
When the TRIANGLE wave is rising the PULSE output is
high and when it is falling the output is low. This signal can
be used for synchronizing external equipment.
12 LFO RST
The LFO RST resets the phase of the LFO to the highest
point of the triangle and then the triangle begins to fall. This
is very useful for creating complex modulation curves or for
synchronizing with external clock.
13 STEPPED
The STEPPED generator is inspired by the Rungler circuit
by Rob Hordijk. It can produce 8 di erent voltages. It
generates new voltage twice per period of the LFO (every
time the direction changes from rising to falling). The
voltage is based on the current state of 3 bits of internal
binary 8 bit shift register. The shift register is shifted with
every new voltage generated. When this happens - based
on the signal at the BIT IN socket - the new bit arriving at the
shift register remains the same (BIT IN is low), is inverted
(BIT IN is not connected) or is generated randomly (BIT IN
is high). It means that when BIT IN is not connected the
STEPPED output generates a 16 step pattern.
